Your favorite (fictional) true-crime podcasters have solved another murder, as Only Murders in the Building has officially wrapped up season 2 and the case of who killed Bunny. We’ve been doing our own investigation into all of the potential suspects of this latest crime throughout the season, but now that the killer has been revealed, we break here to break it all down. SPOILER ALERT if you are not up to date with the comedy series.

For anyone who needs a quick recap, Only Murders in the Building stars Selena Gomez, Steve Martin and Martin Short as true-crime podcast superfans Mabel, Charles and Oliver. When an actual murder takes place in their building, they use their amateur skills to try and solve the case, recording their own podcast (the titular Only Murders in the Building) along the way. This does not endear them to many of their fellow residents, even when they solve the case.

In the final moments of season 1, as the trio celebrates, Mabel goes to get some champagne from her apartment. While she is away, Charles and Oliver receive a text telling them to get out of the building. They go to try and get Mabel, only to find her bloody and kneeling over the dead body of one of their disgruntled neighbors, Bunny (Jayne Houdyshell), though Mabel claims "it’s not what it looks like." The three are then taken into police custody.

Let's dive into who was the killer in Only Murders in the Building season 2.

After revealing herself to really be Becky Butler, the thought to be murdered woman in the podcast that put Cinda Canning (Tina Fey) on the map, Only Murders in the Building season 2 finale showed us more about the life Poppy, ne Becky (Adina Verson), left behind in Oklahoma. She had a father that didn’t appreciate her, a boss who sexually harassed her and the feeling that she was going nowhere fast. She took it upon herself to change course and pursue her dream of becoming a podcaster — one she would pursue by any means necessary.

That first began by helping Cinda create a podcast around her own disappearance/death, fabricated with the assistance of Detective Kreps (Michael Rapaport), who she began a relationship with while he was freelancing on the case in Oklahoma.

With Cinda in need of a follow up podcast to ensure she isn’t a one-hit wonder, Poppy suggests doing one on the long-lost missing artist Rose Cooper, but Cinda shoots it down. So Poppy, with the encouragement of Kreps, takes the initiative to turn it into something Cinda can’t ignore by killing Bunny and painting her Only Murders rivals as the prime suspects.

Looking back, the clues pointing it all to Poppy date back to the final moments of season 1, when she and Cinda are ready to go on the scene as Charles, Mabel and Oliver are arrested. Bunny’s dying message that Mabel thought was "14, Savage" was actually "14 sandwich," which referred to the order that Poppy got at the diner when she met Bunny. Finally, the prints that Detective Williams (Da'Vine Randolph Joy) pulled from the murder weapon belonged to Becky Butler.

Poppy could ultimately not resist confessing when Charles, Mabel and Oliver set the trap where they falsely accuse Alice (Cara Delevingne), fake Charles’ death and make it seem like Cinda is ready to offer Mabel her very own podcast, the thing that Poppy wants so badly. Detective Williams arrives on the scene and arrests Poppy, alongside Detective Kreps already in cuffs. 

We have to say, we found the mystery for this season to be another fun, twisty ride with an ultimately satisfying ending. But, as we see in the final moments of the season, there’s another murder to solve and we can’t wait to try and put the pieces together in Only Murders in the Building season 3.

All of Only Murders in the Building season 2 is now available episodes on Hulu in the US and Disney Plus in the UK.
